About
Dr. Si-Wei Liu is a structural engineering researcher whose work focuses on the analysis and design of non-prismatic steel members, particularly tapered I-section beams and columns. His major contributions lie in developing advanced numerical models for the direct analysis of tapered steel frames, addressing the growing need for efficient, high-strength structural solutions. Notably, his 2020 paper on a mixed-field Timoshenko beam-column element for tapered members has garnered 17 citations, while his 2018 work on modal and elastic time-history analysis of frames with non-prismatic elements has received 14 citations. Dr. Liu’s research is driven by practical engineering challenges—he has firsthand experience applying tapered members in real-world projects, leveraging low-cost robotic welding and high-strength steel plates (over 500 MPa) to create economical alternatives to conventional prismatic designs. His work bridges the gap between theoretical modeling and practical application, making him a valuable contributor to modern steel structure design.
